Ruby crash bringing default http://localhost:3000 page

I reported this previously on the Ruby/Rails ibm_db support page and it was suggested that I post the problem here.

After starting the server with 'rails server' and accessing 'localhost:3000', the expected default page comes up and a few seconds later a popup Window with
"Ruby interpreter (CUI) 1.9.2p290 [i386-mingw32 has stopped working"
and the server appears to have crashed.

On a completely different Windows 7 system I installed Ruby 1.9.2, Rails 3.2.8 and ibm_db 2.5.10.
It crashes Ruby with the same error reported intially.

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
